3)LSSD(Level-Sensitive Scan Design) architecture:将一个latch替换为主从两个latch。 其中mux-scan和clocked_scan,主要用在FF电路,LSSD主要用在锁存器电路,框图见相册。 Test Procedure Files:描述scan circuirty的操作。用STIL语言编写(Standard Test Interface Lauguage)。 Model Flattening:一些DFT有内部自己的mode...
This paper proposes a new DFT architecture, named as Joint-scan. The proposed architecture provides a solution for the test time, test data volume, and test power problems simultaneously. The primary idea here is to bring in the key advantages of serial scan and random access scan in a ...
In addition to reducing the test time by implementing the compression architecture, DFTMAX Shared I/O CODEC also shares the inputs and outputs of the different compression structures in the design and addresses the scan channel limitation at the top level. Conclusion To overcome the growin...
边扫描测试(Boundary Scan)是在20世纪80年代中期,为了解决PCB物理访问问题而发展起来的。1990年2月,成为IEEE标准,分类在标题 “A standard boundary scan architecture and test access port”下。 1、什么是Boundary Scan? 随着大规模集成电路的出现,印制电路板制造工艺向小,微,薄发展,传统的测试已经没有办法满足这...
To resist scan based attacks, this paper proposes a dynamic key security DFT architecture. The DFT structure allows authorised users to extract data using the scan chain in test mode only. Before each test mode is applied, the secure DFT generates the appropriate correct key to ensure that the...

For the scan design, the circuit under test (CUT) in the test mode usually has larger switching activity than in the function mode, causing excessive power dissipation. In this paper, we propose a new Scan Matrix (SM) architecture for the scan-based design to achieve low power testing. The...
